I see that this draft uses a syntax similar to RFC 8145 Trust Anchor
Telemetry RFC (which uses _ta-<hex_id>) albeit without the leading
underscore, i.e. .ta-<hex_id>.

I'd like to propose instead <hex-id>._ta.<domain>

This would allow _ta to be registered as a standalone entry in the
underscore label registry, whilst also avoid the risk of collisions with
"plain" labels that happen to match ta-<hex>

FWIW, I think in retrospect that RFC 8145 should have taken a similar
approach too.
